Hi Lea,
Still awaiting a response.
As you can see from the screenshots Adobe Extension Manager just contains the Addons that I want. All others have been removed from the listing.
On another pc which was having problems logging on in Photoshop cc, your agents reinstalled or updated Creative Cloud because that had apparently not been updated. That resolved that problem. However when Creative Cloud starts it still tries to load removed Addons, It appears you have a problem here with cc or the problem would not be appearing on both pcs. Never had this problem with Photoshop CS6
